In the press release, GlenStar insists the Meadows -- especially the two-story building along Greenville -- is but a "shadow" of its former self and in desperate need of a makeover. Present tenants, many of whom are architects and designers who've sunk tens of thousands of dollars into recent renovations, have argued otherwise as they're being told to move.

Architect Max Levy, who's been in the Meadows for more than 30 years and witnessed first-hand the 1985 demolition of the wing along N. Central Expressway, said in December that to "destroy the other one, it’s like amputating two arms."

GlenStar disagrees.

"Over the last 25 years, the integrity of the Meadows Building complex has been considerably diminished, through building demolition and major alterations to the grounds," says the release, which isn't credit to any single person. "These alterations, combined with significant deferred maintenance, have rendered it a shadow of what its original developer intended. This unfortunate situation is most evident in the remaining annex building, one of two low-rise buildings that flanked the nine-story Meadows Building and original courtyard.

"By implementing a program of thoughtful restoration and preservation, coupled with appropriate urban and landscape planning, the redevelopment plans will celebrate the well-known, nine-story Meadows Building and give it the prominence it has been lacking in recent years. To make way for this vision, the plan entails removal of the annex building in favor of creating a dynamic pedestrian friendly mixed-use site that will highlight the Meadows Building and provide for a significant investment and revitalization of the Greenville Avenue corridor that will benefit the Meadows Building and bring vitality to this property and the surrounding neighborhood."

The press release comes just days before Dallas' Landmark Commission is scheduled to discuss making the building an official city landmark, which would protect it from alteration or demolition without the commission's approval.

GlenStar reps will attend Monday's meeting and make their case to the commission.

Earlier this week, Preservation Dallas asked its supporters to send a letter to the commission that reads, in part, the Meadows Building "has become one of the best examples of the Mid-Century Modern style of architecture. The building is truly unique and one that was a trailblazer for modern office building design of the 1950s and 60s in Dallas."
